Max’s owner, Jonathan Pratt, said he and Max were out on the back porch around 9 p.m. Wednesday when Max heard something in the brush about 100 feet away and took off into the dark to investigate.

“All of a sudden it sounded like dogs fighting, and you could hear him crying. The damage was done and the coyotes went scurrying off,” Pratt said. “I’m shocked because I didn’t think he would survive.”

Pratt rushed Max to the veterinary hospital where the dog underwent a four-hour surgery to repair the muscle and skin.

“He’s got an uphill battle,” Martinez said, noting that it was the worst coyote attack they’ve seen where the animal survived. “In the best case scenario, he’ll be here for another week.”

Comparing the attack to blunt-force trauma, Martinez said there are a number of ongoing concerns, including bruising, internal bleeding and infection. Although Max is in tough shape, Martinez said he’s lucky his internal organs weren’t punctured.

“He’s big for his breed, and that worked in his favor. Usually these dogs are half the size,” Hospital Manager Gerry Martin added.

Living in a rural area, Pratt said it’s common to hear coyotes in the distance, but he’s never seen them so close to his house.

Marion Larson, the chief of information and education for the state Division of Fisheries and Wildlife, said it’s not uncommon for Eastern coyotes to go after larger dogs, but usually it’s a matter of protecting their territory, rather than hunting.

“I’ve heard of coyotes going after a German shepherd, but that’s more about territory or feeling threatened,” she said. “Maybe there were young pups nearby.”

Larson said it’s important people know that coyotes are throughout the state, and it’s important to go outside with your pet, preferably on a leash.

“Coyotes are intelligent animals, and they start to figure out schedules,” she said. “Human beings are considered a threat, so the best thing you can do for your pet is be out there and close by.”

Max’s medical expenses are expected to cost as much as $7,500, and a gofundme page has been set up to assist.
